The UTC 4N40 is an N-channel mode power MOSFET using UTC’ s advanced technology to provide customers with planar stripe and DMOS technology. This technology specializes in allowing a minimum on-state resistance and superior switching performance. It also can withstand high energy pulse in the avalanche and commutation mode.
The UTC 4N40 is universally applied in electronic lamp ballast based on half bridge topology and high efficient switched mode power supply.
* High switching speed
* RDS(ON)=1.5Ω @ VGS=10V
* 100% avalanche tested
